PRECAUTIONS TO BE TAKEN DURING MAINTENANCE
60
2.8.21 PRECAUTIONS CONCERNING TECHNOPOLYMERS AND ELASTOM-
ERS
DANGER
q
Some components of the machine contain polymers and elastomers (Viton sealing rings, Teflon rings,
piston seals made of fluoroelastomers, electric cable insulating materials, etc.).
At room temperature and up to approximately 200°C these materials can be handled without taking any
precautions, since they are completely inert.
However, if these materials are burnt, they release highly toxic gases.
Once these materials have cooled down, they must be collected in tight bags, using heavy waterproof
gloves; gloves and materials must be disposed of in a differentiated manner in compliance with the laws
in force.
The contaminated part of the machine must be washed with highly alkaline detergents and then with a
solution made of detergent and water.
q
Avoid burning seals, electric cables, sealing rings.
q
Dispose of elastomeric and polymeric waste according to
the regulations in force.
q
Do not touch any burnt elastomeric or polymeric waste and
in case of accidental burning avoid inhaling the toxic gases
produced.
q
In case of contact with the skin, immediately rinse with a so-
lution made of water and an alkaline detergent for about 30
minutes and then contact a poisoning treatment center with-
out delay.
2.8.22 PRECAUTIONS TO BE TAKEN
WHEN INFLATING THE TYRES
q
Always bear in mind that tyres can burst while being inflated,
causing serious accidents.
q
Before inflating the tyres, always check the wheel rims and
the tyre sidewalls and tread for dents, cuts, broken plies or
other defects.
q
Have the tyres checked and serviced by specialized person-
nel.
q
Inflate the tyres using a protection structure and a pneumatic
inflating gun with extension complete with pressure gauge.
q
Make sure that there is nobody in the vicinity before starting
to inflate a tyre. Stand beside the tyre to inflate it.
q
Do not exceed the inflation pressures prescribed for the sin-
gle types of tyre and make sure that all the tyres have the
same pressure.
